Q & A
What is reliability engineering?
-Reliability engineering is defined as the probability that an item or system will perform its required functions under stated conditions for a specified time interval.
What are the key terms in the definition of reliability?
-The three key terms in the definition of reliability are probability, required function, and a specific time interval.
How does reliability relate to statistical principles?
-Reliability is inherently probabilistic and non-deterministic, relying on statistical data to determine how well a component or system can function over time.
What factors influence the reliability of a component?
-Factors such as environmental conditions, temperature, and stress can significantly affect the reliability of a component.
What are the two types of variables in statistics mentioned?
-The two types of variables are continuous random variables, which can take any value within a range, and discrete random variables, which take specific values.
What is the Probability Density Function (PDF)?
-The Probability Density Function (PDF) describes the likelihood of a continuous random variable falling within a particular range of values.
What does the Cumulative Distribution Function (CDF) represent?
-The Cumulative Distribution Function (CDF) represents the cumulative probability of a random variable taking a value less than or equal to a specified value.
How is reliability function related to failure probability?
-The reliability function can be calculated as one minus the cumulative distribution function of failure probability, indicating the likelihood that a component will function successfully over a time period.
What is MTBF and how does it relate to reliability?
-Mean Time Between Failures (MTBF) is a measure used to indicate the reliability of a system, calculated as the average time between failures of a system during operation.
What role does live testing play in determining reliability?
-Live testing provides more accurate data for reliability analysis compared to laboratory testing, as it reflects real-world usage conditions and stresses.
